初识yeoman

时间:2025-02-19 09:03:32

最近开始新项目,在项目构建上面寻找合适的东西,grunt,bower到发现yeoman;学习了下,把一些东西记录下来然留着以后用.

1.什么是Yeoman

Yeoman是Google的团队和外部贡献者团队合作开发的,他的目标是通过Grunt(一个用于开发任务自动化的命令行工具)和Bower(一个HTML、CSS、Javascript和图片等前端资源的包管理器)的包装为开发者创建一个易用的工作流。

Yeoman的目的不仅是要为新项目建立工作流,同时还是为了解决前端开发所面临的诸多严重问题,例如零散的依赖关系。
  • yo - the scaffolding tool from Yeoman
  • bower - the package management tool
  • grunt - the build tool
初识yeoman
Yeoman就是快速创建webapp,初始化了各个版本的文件目录有关bower和grunt的配置.初始化过程中以询问模式处理.
2.安装Yeoman
依赖:Nodejs 如果需要使用sass 要安装Ruby
在安装玩完 nodejs的情况下
终端运行:
npm install -g yo
npm install -g grunt-cli bower

3.install 基本的项目模板(generator);

yeoman提供了一些基本的模板 如:

generator-webapp

generator-angular

使用命令添加

npm install generator-angular -g 

more

4.可以创建自己的 generator

creat

5. generator-angular 示例

初始化项目

i 初始化一个以angualr为基础的项目

yo angular

终端显示如下:

根据需求选择你需要的依赖

一段时间后项目生成如下结构

其中很多配置文件yeoman都给我们自动创建好了 比如package.json  Gruntfile.js .gitignore 等配置文件.

到这里项目创建成功了!

6.分析下 Gruntfile.js

这是创建的示例Gruntfile.js

// Generated on 2014-07-02 using generator-angular 0.9.1
'use strict'; // # Globbing
// for performance reasons we're only matching one level down:
// 'test/spec/{,*/}*.js'
// use this if you want to recursively match all subfolders:
// 'test/spec/**/*.js' module.exports = function (grunt) { // Load grunt tasks automatically
require('load-grunt-tasks')(grunt); // Time how long tasks take. Can help when optimizing build times
require('time-grunt')(grunt); // Configurable paths for the application
var appConfig = {
app: require('./bower.json').appPath || 'app',
dist: 'build'
}; // Define the configuration for all the tasks
grunt.initConfig({ // Project settings
